🔍 Key Concepts

• LRIT (Long-Range Identification and Tracking) requirements under SOLAS Chapter V, Regulation 19-1 • Meaning of APR (automatic position report) and what the terminal does with it (transmit vs receive) • Standard time interval required for routine LRIT position reports

💭 Think About

• First, decide whether an LRIT terminal’s primary job is to send information out, receive information in, or both—how does the system help flag States track ships? • Think about how often a ship’s position needs to be updated for “long-range” tracking: is 6, 8, 12, or 24 hours realistic for safety and monitoring? • Look carefully at the words transmit versus receive in the options and match them to what you know about LRIT terminals.

✅ Before You Answer

• Confirm from SOLAS V/19-1 what the maximum interval between LRIT position reports is (in hours). • Check whether LRIT terminals are required to transmit APRs automatically, or to receive them from shore, or both. • Make sure the correct choice includes all three functions: ability to be configured for automatic APRs, a correct reporting interval, and the ability to transmit a position report (PR) on request.
